Problems solved by technology

[0004] Most of the current cooling devices for lasers are to install a heat sink at the end of the laser, and then install a fan at the back. The airflow output by the fan blows to the heat sink and flows out. The convection area is not large enough, and the convection speed is not fast enough.
Therefore, the heat dissipation effect is not good, which affects the improvement of the beam quality and power of the laser and the development of laser miniaturization.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for a laser. Background technique [0002] During the working process of the all-solid-state laser, the pump light is focused in the laser crystal to provide energy for the laser oscillation, but factors such as quantum defects and non-radiative transitions in the crystal cause a large amount of heat to be generated, that is, part of the energy of the pump light Instead of being converted to laser output, it becomes waste heat in the crystal, resulting in thermal effects of the crystal. [0003] The thermal effects of laser crystals mainly include thermally induced birefringence, thermal depolarization and thermal lensing. The temperature tolerance range of nonlinear crystal phase matching is limited, and the temperature requirement is high, so the heat generated in the laser seriously affects the output power, polarization state and beam quality of the lase...
